Abstract (en)
[origin: WO2012140373A1] The invention relates to a fuel circuit (10) for a turbine engine, comprising: a low-pressure pump (12), a high-pressure pump (14), and a low-pressure duct (22) connecting the low-pressure pump (12) to the high-pressure pump (14); a high-pressure duct (26) fed by the high-pressure pump (14) and in which a component (20) is arranged; and means for controlling the operation of said component (20). The circuit is characterized in that it comprises a valve (34) that can seal a segment (30, 32) of the duct (26) when the pressure in the low-pressure duct (22) is lower than a predetermined threshold value, and the control means can detect that the valve (34) is at least partially sealing said segment (30, 32).
